IMPROVEMENT IN CARRIAGE-WHEELS.

Specification forming part of Letters Patent N 0. 166,191, dated August3, 1875; application filed May 22, 1875.

To all whom it may concern:

Be it known that I, DEXTER CUSHMAN, of Milford, of the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Carriage-Wheels; and do hereby declare the same to befully described in the following specification and represented in theaccompanying drawings, of which- Figure l is a side view, and Fig. 2 atrans verse section, of a wheel having my invention. Fig. 3 is a side"iew, and Fig. 4 an' edge View, of one of the felly-recess caps.

The object of the invention is to enable the felly to be readilyseparated from the spokes, or the latter set up and tightened relativelyto. the felly, as occasion may require.

In the drawings, A denotes the hub, and B B B a series of spokes fixedtherein and radiating therefrom.

On each spoke there is driven, at its outer end, a metallic ferrule, O,and up to a parti tion, at, extending across such ferrule. the outer endof the ferrule, and up to the partition a, a male screw, D,is.screwed,-it being projected beyond the ferrule, and provided with anut, E, beyond which it also extends into a socket or recess, 12, madein the felly H. This socket or recess is open on one side of the fellyand closed on the other, as shown in Figs. 5 and 6, the former of whichis an inneredge view, and the latter a side view, of part of the fellyhaving such a recess.

In ady'ance of the nut, and on the screw, is an elongated plate orwasher, F, formed as shown in side view in Fig. 7, which is to befastened to the inner periphery of the felly by screws going throughholes 0 c in said washer. Between the felly and the washer is thespanner or recess-cap G, (shown more particularly in Figs. 3 and 4,) itbeing notched, as represented at d, to enable it to he slid upon and.

Into

By setting back each of the nuts on its screw, removing the fasteningsof the washers, and slipping back the several spanners, the felly may bereadily separated from the spokes.

From the above it will be seen that in case of shrinkage of either ofthe spokes in the hub, or otherwise, so as to work loose, it can beeasilyset up or tightened.

The spanner G may be composed of two plates, f g, formed as shown inFigs. 8 and 9, (Fig. 8 being a top view, and Fig. 9 being an edge view,of them,) one lapping a short distance on the other, and each havingholes I l in its lapping part, to receive the fastenin gscrews by whichit is to be fixed to the felly.

Some of the spokes may be without the washer, but have a spanner ofcommon kind, as shown at h, curved transversely to fit to and around thefelly.

I do not claim a screw, nut, and a ferrule made and applied to a wheelspoke and tire in manner as shown in either ofthe United States PatentsNos. 101,948, 114,307. In my wheel the ferrule has a partition extendedacross it, and above such partition it is provided with a female screwto receive a separate male screw, D, extended up into the recess 1) ofthe tire, and provided with anut, E, all as hereinbefore specified. Withmy invention I unite the advantagc of having the nut outside of thespanner with the male screw separate from the ferrule, and capable ofbeing readily removed in case of breakage, and being substituted byanother, without the necessity of changing the ferrule.

I therefore claim-- The ferrule 0, provided with the partition a and thefemale screw, to receive and support the separate male screwD, incombination with said screw D, the spoke B, the nut E, and the tireprovided with the recess 1) and spanner G, all as set forth.
